Introduction
This manual provides detailed instructions for the setup, operation, and maintenance of your OLEVS 3661 Men's Quartz Watch. Designed with a light luxury aesthetic, this watch features a multi-function chronograph, moon phase display, date window, and luminous hands, all housed in a durable, waterproof tonneau case.
Setup
Setting Time and Date
The watch crown has two positions for adjustment. Refer to the diagram below for visual guidance:

- To Adjust Date: Gently pull the crown out to the first gear position. Rotate the crown to set the desired date.
- To Adjust Time: Pull the crown out to the second gear position. Rotate the crown to set the desired time.
- Once set, push the crown fully back into its original position to secure the settings and maintain water resistance.
Strap Adjustment
For models with a metal bracelet, adjustment may require specialized tools to remove or add links. It is recommended to have this done by a professional watch technician to avoid damage. For leather straps, adjust the buckle to fit your wrist comfortably.
Operating Instructions
Chronograph Functions
Your OLEVS 3661 watch features a multi-function chronograph for precise timing. The sub-dials indicate 60 minutes timing and a 60-second timer.
- Start/Stop Chronograph: Press the top button on the side of the watch case to start the chronograph. Press it again to stop.
- Reset Chronograph: Press the bottom button on the side of the watch case to reset the chronograph hands to zero.
Moon Phase Display
The watch includes a 24-hour lunar phase display, providing an aesthetic and functional complication. This display typically advances automatically with the time.
Luminous Function
The watch features a high-definition luminous function on its hands and markers, allowing for easy time reading in low-light conditions. Exposure to natural or artificial light charges the luminous material.

Water Resistance (30m / 3ATM)
This watch is rated for 30 meters (3ATM) water resistance. This means it is suitable for daily use, such as accidental splashes, hand washing, and light rain. It is important to note the following:
- DO NOT wear the watch for swimming, diving, or showering.
- Avoid exposing the watch to hot water or steam, as this can compromise the water-resistant seals.
- Always ensure the crown is fully pushed in after any adjustments to maintain water resistance.
Maintenance
Cleaning
- Regularly wipe the watch case and strap with a soft, dry, lint-free cloth to remove dirt, dust, and sweat.
- For metal bracelets, a soft brush and mild soapy water can be used. Ensure to rinse thoroughly with clean water and dry immediately with a soft cloth.
- Avoid using harsh chemicals, solvents, or abrasive cleaners, as these can damage the watch's finish or seals.
Water Resistance Care
- Always ensure the crown is fully pushed in after any time or date adjustments.
- Avoid exposing the watch to extreme temperature changes (e.g., hot shower immediately followed by cold water), which can affect the integrity of the water-resistant seals.
- If you notice any fogging or condensation inside the watch crystal, have it inspected by a professional watch technician immediately.
Battery Replacement
As a quartz watch, your OLEVS 3661 is powered by a battery. When the watch stops running, it indicates the battery needs replacement. This should be performed by a qualified watch technician to ensure the correct battery type is used and the watch's water resistance is maintained after opening and re-sealing the case back.
Troubleshooting
Watch Not Running
- Check if the crown is fully pushed in. If it is pulled out, the watch will not run.
- If the crown is pushed in and the watch is still not running, the battery may need replacement. Consult a professional watch repair service.
Incorrect Time/Date
- Refer to the 'Setting Time and Date' section to correctly adjust the watch. Ensure the crown is fully pushed in after adjustment.
Fogging Inside Crystal
- Minor fogging that dissipates quickly is usually due to temperature changes and is normal.
- Persistent fogging or visible water droplets inside the crystal indicate a breach in water resistance. The watch should be serviced immediately by a professional to prevent further damage to the movement.
